Pregnancy Termination for Dogs

Safe and effective termination of pregnancy is possible in both the bitch and queen by the administration of prostaglandin F2α (a natural hormone) at 0.1 mg/kg, SC, tid for 48 hr followed by 0.2 mg/kg, SC, tid to effect (until all fetuses are evacuated as confirmed by ultrasonography). Treatment times can reach 14 days.

For a dog in heat and addressed to her male, the time is always right for love. For its owner, maybe not much. You might have plans to raise a lady’s puppy or maybe not get her sterilized in time, but the bottom line is that you’re not ready for the puppy. Your veterinarian can work with you to end her pregnancy.

Mating does not always mean pregnancy
Before you worry about ending your dog’s pregnancy, you’ll need to confirm her pregnancy. Just because she has an intimate moment does not mean that she is conceiving. According to Merck’s veterinary guide, 60 percent of stray dogs are unimaginable. The veterinarian can confirm the pregnancy around 20 to 22 days after ultrasound reproduction and palpation in the abdomen. Earlier you can confirm pregnancy better; trying to end after 40 days endures the potential shock of connecting puppies anyway. Your veterinarian can use a similar test for a home pregnancy test about 30 days after mating to confirm pregnancy.

Sterilization during pregnancy
If you plan to sterilize your dog, sterilizing her and aborting the fetuses will end her pregnancy and ensure she will not become pregnant again. Natural sterilization surgery requires removal of the uterus and ovaries. If she is pregnant, the fetus is taken with the uterus. For a dog that will not be raised, this is usually the best option, although it does have some risks. The blood vessels of the reproductive system are more difficult to attach when carrying the dog, which makes surgery longer and more expensive. Also, recovery time takes slightly longer than routine sterilization.

Prostaglandins and glucocorticosteroids
There are three types of medications available to end a dog’s pregnancy without sterilizing it: estrogen, prostaglandins, and glucocorticoids. The vet will make the best choice, based on your dog’s health and location. Prostaglandins reduce the level of progesterone to end a pregnancy. Pyometra, uterine infection, is the most serious potential side effect of prostaglandin. The dog must stay in the veterinarian for treatment that will last four to seven days. Prostaglandins do not always work and sometimes only part of the garbage is miscarried, so ultrasound is necessary to ensure that the pregnancy is completely aborted. Cortisone is most often used in late pregnancy and is not always effective. Since these medications are used in later stages of pregnancy, the dog often delivers dead puppies, which can be painful for them. Since a high dose is necessary, common side effects include increased thirst and urination, as well as gasping and occasional incontinence.

Estrogen problems
Estrogen is still an option but is rarely used because it is very ineffective and carries a risk of causing uterine suppuration. Other possible side effects of estrogen include bone marrow suppression and an extended state of estrogen. Estrogen is only in the early stage of pregnancy – when it is too early to confirm its condition – and it works by preventing fertilized eggs from implanting in the womb. Since the risk of side effects is so great and there is no way to confirm pregnancy, many veterinarians will not use this method because they are likely to endanger the dog without reason.

Myths vs facts
If your dog encounters an unwanted romantic encounter, you will not finish the post-intercourse perfusion by carrying her. The only thing you can do is wait until the vet can confirm your suspicions. Meanwhile, keep her in a state of heat so that she cannot entertain more male suitors. If you plan to sterilize it, talk to your vet to make an appointment after it leaves the heart. If you decide to go ahead and become very, get ready for the antenatal and postnatal care that you will have to receive, as well as find good and responsible puppy homes. If your dog has a miscarriage, talk to your vet to find out what behavior to look for as the dog heals.

Can you terminate a dog’s pregnancy?
If it is important that the female animal is bred in the future, the pregnancy can be terminated without sterilizing her. This entails the use of medications to end the pregnancy during the second “trimester,” about 30-40 days into the pregnancy.

What can you give the dog to end the pregnancy?
Prostaglandin F2alpha (PGF, Lutalyse (R), dinoprost tromethamine) is a hormone that stimulates muscular decomposition in many species, including dogs. Because progesterone is necessary throughout gestation for maintenance of pregnancy, PGF-induced death of the corpus luteum leads to termination of pregnancy.
